Muminda yekufambisa mafuta negasi, mapurojekiti ekuchengetedza mvura uye kuvaka mapaipi emumaguta, mhando yerukoko rwekunze rwemapaipi esimbi runodzivirira ngura ndiyo inosarudza zvakananga hupenyu hwebasa uye kuchengetedzeka kwemapaipi. Chii Chinonzi 3LPE Coating - Mhinduro yemubvunzo uyu iri pakati petekinoroji yemazuva ano yekudzivirira ngura pamapaipi. Sisitimu yekuputira yepolyethylene ine mativi matatu (3LPE), ine hunhu hwayo hwakanaka hwemakanika, kuramba ngura uye kugadzikana kwenguva refu, yave mhinduro yekuenzanisa yekudzivirira ngura pamapaipi muindasitiri yepasi rose yemapaipi esimbi.
Sisitimu yekuputira 3LPE inowanzo kuve nematatu matatu: chigadziko chepasi chinova fused epoxy powder (FBE), ine kunamatira kwakanaka uye cathodic resistance; chidimbu chepakati i copolymer adhesive layer, yakavakirwa pachikamu chepamusoro chezasi; chidimbu chepamusoro i polyethylene layer yakaburitswa iyo inodzivirira firimu ye coating system kuti idzivirire michina zvakanyanya uye inodzivirira zvakanyanya. Chimiro chakadaro che layer composite chinobvumira 3LPE coating kuchengetedza mapaipi esimbi zvakavimbika mumamiriro akaoma epasi pevhu uye munzvimbo dzakaoma kwemakumi emakore. Mukushandiswa chaiko, sarudzo ye3LPE Coating Ukobvuchinhu chakakosha chekusimbisa kushanda kwependi. Zvichienderana nezvinodiwa, mapendi ePE anoburitswa mufekitori ane mativi matatu uye mapendi ePE ane mativi akawanda anogona kushandiswa pamapaipi esimbi uye mafittings. Kazhinji, ukobvu hwependi hwese hunogadzirwa zvakasiyana nedhayamita yepombi yesimbi, nzvimbo yebasa, hupenyu hwebasa, uye mwero weinjiniya.
Nzira yekuziva sei ukobvu hwakakodzera hwe3LPE coating? Pfungwa dzinotevera ndidzo dzakakosha dzekufunga:
Dhayamita yepombi uye ukobvu hwemadziro
Pamapaipi ane dhayamita yakakura, anosangana nekumanikidzwa kukuru kwemuchina panguva yekufambisa, kuvaka, uye kuzadza. Nokudaro, machira akakora anowanzo dikanwa kuti agare akasimba uye akasimba.
2. Nzvimbo Yebasa
Kune zvikamu zvemapaipi zvinopfuura nemunzizi, nzvimbo dzine ivhu kana matombo ane ngura yakawanda, jira rakakora rinofanira kusarudzwa kuti riwedzere kusimba kweganda uye kudzivirira ngura.
3. Zvinodiwa zveMaitiro neMagadzirirwo
Nyika dzakasiyana uye zviyero zveindasitiri zvine mitemo chaiyo pamusoro pekukora kwe3LPE coatings. Kazhinji, ukobvu hwekunze kwepolyethylene layer hunowanzova pakati pe1.8mm ne3.7mm. Kukosha kwacho kunofanirwa kusimbiswa zvichienderana nezvinodiwa neprojekti.
4. Mamiriro Ekuvaka Nekufambisa
Kana pombi ichida kutakurwa kure kana kusimudzwa kakawanda, kuwedzera ukobvu hwepurasitiki zvakakodzera kunogona kuderedza njodzi yekukuvara kunokonzerwa nekurovera.
Mukugadzirwa kwayo, mutsetse wedu wekugadzira coating we3LPE unotevedzera zvinodiwa zvekugadzira simbi. Kubva pakugadzirisa pombi yesimbi pamusoro, kupfapfaidza upfu hwe epoxy, kushandisa namatidza kusvika pakugadzira polyethylene extrusion, nhanho imwe neimwe inofanirwa kutariswa uye kuyerwa kweukobvu kuti ive nechokwadi chekuti coating yacho inosangana nezvinodiwa zvekugadzira.
Kunzwisisa "Chii chinonzi 3LPE Coating"uye kusarudza nesainzi 3LPE Coating Thickness chinhu chakakosha pakuona kuti sisitimu yemapaipi inoshanda zvakachengeteka kwenguva refu. Ticharamba tichipa vatengi vepasi rose mhinduro dzesimbi dzinodzivirira ngura dzinosangana nezvinodiwa uye dzakakodzera mamiriro chaiwo kuburikidza nemaitiro akaomarara uye mhando yakavimbika."
